Stop using learning module

Hi,

I don't have much experience in the learning module. A client of mine is no longer using it and doesn't intend to do so anymore. So they want to negotiate with Oracle on replacing this module with another one. He asked me to un-enroll all users from the learning module. As all system users are automatically created or granted access to the learning module. This users count is appearing on the learning module at Oracle's side and therefore cannot be stopped.

I would appreciate if anyone can offer some clarifications as I lack the enough knowledge to affirm his statements.
